• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wing ian) OR (liang sun))) OR (dong di)) et a last first ((iso chang) OR (woo chang)) c ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wing ian) or (liang sun))) or (dong di)) et a last first ((iso chang) OR (woo chang)) c ;*".
